CONOTRACHELUS. AIT 
like the head, the antenne inserted towards the tip, joint 2 of the funiculus much shorter than 1. 
Prothorax transverse, rounded at the sides anteriorly, narrowed and constricted in front, strongly 
bisinuate at the base; very coarsely, rugosely punctate, carinate down the middle of the anterior half. 
Elytra rather long, subparallel in their basal third, the humeri rounded externally ; coarsely seriate- 
punctate, the interstices slightly rugulose, 3, 5, 7, and 9 moderately costate, the ridge on 1 interrupted 
below the base. Prosternum very short before the anterior coxe, the sulcus shallow. Mesosternum 
flattened between the coxse, protuberant and bituberculate in front. Ventral segments sparsely, finely 
punctate. Legs very stout and rugose; femora strongly clavate, with a stout triangular tooth and a 
minute one exterior to it; tibie strongly sinuate within ; tarsal claws with a long tooth. 
Length 64, breadth 3 millim. (¢?) 
Hab. Panama, Tolé (Champion). 
One specimen. An isolated form, oblong in shape, with the prosternum very short 
before the anterior coxe, and the sulcus shallow; the mesosternum protuberant ; the 
rostrum short, flattened at the base above, very rugose, and widened beyond the middle, 
the base of the scrobes being visible from above. 
138. Conotrachelus nodifer, sp.n. (Tab. XXI. figg. 1, 1a.) 
Oblong, robust, opaque, black, the antenne and tarsi obscure ferruginous ; the vestiture dense above, reddish- 
brown on the prothorax, and brownish on the elytra, the latter with a large sordid-ochreous humeral 
patch, limited inwards by an oblique white streak at the base of the third interstice and outwards by a 
dense, oblique, attenuate, white fascia below the shoulder, that of the under surface and legs sparse, 
brownish, with narrow white scales intermixed, the mesosternal side-pieces with an oblique ochreous 
streak, the femora subannulate. Head rugulosely punctate, depressed between the widely separated 
eyes ; rostrum a little shorter than the prothorax, feebly curved, very stout, depressed at the base above, 
densely rugulosely punctate, obsoletely unicarinate at the base, the antenn inserted towards the apex, 
joint 2 of the funiculus shorter than 1. Prothorax about as long as broad, narrowed and constricted in 
front and narrowed behind, the sides obsoletely bidentate, the base very feebly bisinuate; rather 
sparsely, finely punctate, the interspaces rugulose, the disc binodose before the middle and at the apex. 
Elytra oblong, subparallel in their basal half, broadly rounded at the apex, slightly constricted below the 
shoulders; interruptedly seriate-punctate, the interstices dull, 3 with a series of four very stout, oblong, 
granulate tubercles, and 5 and 7 with scattered smaller tubercles, the others with small conical 
prominences. Beneath opaque, finely punctate. Mesosternum conically protuberant in front. Legs 
very stout, short, rugose; femora clavate, acutely unidentate ; tibise broad, compressed, sinuate; tarsal 
claws with a very long tooth. 
Length 61, breadth 3,5 milim. (d?) 
Hab. Mexico, Toxpam (Sal/é). 
One specimen, partially abraded. A species of oblong form, with a short, stout 
rostrum, conically protuberant mesosternum, strongly nodose elytra, and broad, flattened 
tibie. It is extremely like C. lewcostictus, Boh., from Colombia (the type of which I 
have seen), having a similar dense, oblique, chalky-white fascia below the shoulders of 
the elytra, but wanting the cluster of four small white spots on each side of the suture 
towards the apex; the mesosternum, however, is conically protuberant (instead of 
being deeply excavate) in front, the prominences on the elytra are more swollen, and 
the sete are absent.
